Abstract: IMPROVED GRAVITY DEFROST                 ABSTRACT OF THE DISCLOSURE             A reverse air cycle type heat pump is provided that utilizes a refrigeration system having a unidirection refrigerant flow wherein the condenser and evaporate retain their functions, but the air directed across them is redirected for different operations.   The refrigeration system employed in the air cycle type heat pump is further provided with a secondary defrost circuit that includes the system liquid line and a conduit having a valve which permits refrigerant flow to bypass the compressor upon termination of compressor operation.  A sensing means associated with the system expansion device is arranged on the suction line in a manner that allows the expansion device to regulate the flow of refrigerant through the liquid line in the normal manner when the compressor is operating, while allowing unrestrictive refrigerant flow through the liquid line when compressor operation terminates and the system pressure differential is equalized.  This defrost circuit causes the relatively cold refrigerant in liquid phase in the evaporator with the flow continuing until the defrost process is completed.

Abstract: ABSTRACT           The thermodynamic process of  uniting hydrocarbon liquid fuels and the oxygen of the combustion air preparatory for combustion, is a very complex process as anyone well versed in the current state of the art can testify.  The fact that the hydrocarbon liquid fuel supply of the world is a finite, and rapidly depleting resource, with the    of a never ending price esculation, is becoming the increasing concern of everyone.  Also the tremendous increase of harmful hydrocarbon pollut-ants in the atmosphere in most of the larger urban centres has created tremendous respitory and other health related problems for many people. The ever increasing financial burden, that is becoming very difficult for most of us to bear.  The necessity of conserving a rapidly depleting supply of liquid hydrocarbon fuels should be of paramount importance to everyone.  The reduction of harmful hydrocarbon pollutants in the atmosphere of our cities is also a necessity.    The process as defined in this invention can combust all of the liq-uid hydrocarbon fuel, with all of the oxygen in the combustion air, to produce heat (usable power of energy).  Because all of the liquid hydro-carbon fuel is burnt, (enters in to the combustion process), the prod-uction of hydrocarbon pollutants is minimal.    Because all of the fuel charge can produce usable energy, the fuel efficiency of this process is much improved over the process in curr-ent use.  This new process can provide all the users of liquid hydro-carbon fuels, financial saving, while practically eliminating the prod-uction of harmful hydrocarbon pollutants in the exhaust gases, from the devices where this process is used.  The increased fuel efficiency of this process can give the scientists of the world some much more needed time to perfect the processes, that must be found in the use of alternate forms of energy, before our supply of liquid hydrocarbon fuels is exhausted.

Abstract: Jacono and Mumper Case 1 IMPROVED PROCESS FOR PREPARATION OF AQUEOUS SOLUTIONS OF WATER-SOLUBLE POLYMERS            Abstract of the Disclosure An improved process is provided for rapidly dissolving water-soluble polymer gels in which the gels are subjected to the steps of extrusion, cutting of the extruded gels, forming a slurry of gel particles, subjecting the slurry to high shear forces, and finally mixing the resulting slurry and water to form a dilute aqueous solution of polymer.  The improvement comprises cutting of the water-soluble polymer gel, prior to extrusion, into pieces of gel of a size which are small enough to fit into space defined between adjacent flights or the extruder at the feed inlet of the extruder.  The process enables dilute aqueous solutions to be prepared on a batch or continuous basis with good reproducibility of polymer concen-tration in the solution being prepared.

Abstract: CYLINDER CONSTRUCTION FOR A PRINTING PRESS                 ABSTRACT OF THE DISCLOSURE        A cylinder for a printing press in which the gap for receiving the ends of a plate or blanket is skewed at an angle with respect to an axial length on the surface of such cylinder such that streaking of the printed product as is visible to the human eye is essentially eliminated.  Such improved cylinders have a linear skew width greater than the linear gap width with the trailing end of the trailing edge of the gap being located opposite a non-gap area of the other of such cylinders cooperable therewith when such gaps are in their full overlying position.  Such improved cylinders have a non-rotative relative motion when the gaps cross over each other such that the cylinders gradually enter into a zone of decreased pressure therebetween and gradually exit from such zone whereby axial deflection of the cylinders is minimized.  Such improved cylinder is particu-larly suited for a blanket cylinder, a pair of blanket cylinders or plate cylinders or the well known combinations of blanket and plate cylinders.  Further, since the gaps are skewed, a plate or blanket in the form of a parallelogram is provided to improve the mounting of such a plate or blanket to a cylinder having a skewed gap of this invention.

Abstract: ABSTRACT OF THE DISCLOSURE        The disclosed method is one for applying an opaque screening area (46) to a surface of a glass sheet (40). The method is initiated by applying to the surface of the glass sheet a masking material (42) which defines the edges of the opaque screening area.  The masking material is nonreactive with the glass surface and is heat decomposable into products which can be removed from the glass surface without damage thereto.  The masking material extends away from the defined edges of the opaque screening area to provide a wide area of masking material.  A ceramic-containing material is applied on areas of the surface of the glass sheet to which the opaque screening areas are to be applied.  The ceramic-containing material also coats at least a part of the masking material.  The glass sheet is heated to decompose the masking material so that it and any ceramic material overlying it can be removed from the surface of the glass sheet and to heat fuse the fusable components of the ceramic material to the surface of the glass sheet thereby to form the opaque screening area.  The decomposed masking material and any ceramic material over-lying it are removed from the glass sheet so that the opaque screening area is defined by a sharp edge which had been defined by the masking material before its removal.

Abstract: ABSTRACT OF THE DISCLOSURE      A method for electroslag welding of railroad rails under field conditions employs a special mold bottom member and a special guide tube structure.  The mold bottom member includes a metallic insert which is supported by heat-insulating means, e.g. ceramic material in a cavity in a bottom copper block.  The ceramic effectively heat insulates the insert from the copper block so when arcina takes place at the start of the welding, the heat is retained by the insert, which forms part of the weld. The guide tube structure is flared toward the bottom and guides  two continuously fed electrodes.  The structure includes  wing-like members near its bottom end.  The bottom of the structure is designed with sharp corners, so that when arcing takes place some of the guide structure metal melts to form a uniform layer of molten metal, which aids in the melting of flux into a slug bath of uniformly distributed temperature.

It is slurried up several times by means of molten ammonium nitrate or a mixture of ammonium nitrate/urea at 135-200°C together with the aherent components like ammonium nitrate, guanidine nitrate and by-products like triazenes.  Hereby the components adherent to the catalyst are replaced and removed by subsequent filtration.
